RENNtech or Kleeman ECU Flash
Is it worth it? $795 for Kleeman or $1195 for Renntech Ecu Flash?

I think it would be worthwhile if they can prove a stock to flashed dyno chart to see the difference on BOTH M272 motors. Also consider what they do for after-service ecu modifications as in just in case your dealership resets your ECU after servicing.

Kleeman and Renntech can re flash the ecu if the dealer re flashes it. I am still undecidable what to do. Ty Richard

Awesome. Hope this opens the floodgates to more people getting tunes and aftermarket stuff. I know a stock C350 get's 225~ rwhp and I'm curious on the C300.

Don't they give you like a 1 or 2 year warranty for the re-flash?
What do you do after the warranty is up and you get re-flashed?
Pay for the flash again?
I'm also interested in the Kleeman ECU tune.

Just as an fyi, the Carlsson flash includes a warranty on everything you will be voiding in your manufacturer's warranty.. which is everything from the air intake to the exhaust tip.
